Some characters can cause overflow from signs

Some non-english characters looks like isn't handled properly on signs and end ups with stuff like in screenshots. I tested ğ, ş, ı overflows a lot from right, ü, ç, ö overflows a bit from left.

Note: I did that on 0.15.2, i don't know if still happens in 0.15.6. I'll update and test on it too. I couldn't select 0.15.2 as affected version because it wasn't on list.

Edit: Can confirm that happens in 0.15.6 too.
